The design for the crank rod system of a Emery wheel machine repaired and projector
Abstract:Hard alloy is high hardness of infusible metal carbide powder for main components microns，Nickel or cobalt in molybdenum as binder，In a vacuum furnace sintering furnace or hydrogen reduction of powder metallurgy products。Hard alloy used to make drilling tools, mining tools, drilling tools, measuring tools, measuring tools, wearing parts, metal cylinder liner, precision bearings and nozzle, etc. Because of the extensive application of carbide, to trim carbide grinding wheel is increasing. Diamond grinding wheel is energy-saving and environmental protection products, the use of safe, simple operation, can significantly improve the production efficiency and product quality, reduce cost, manufacturing time very easily accepted by operators. With the development of industry, more and more carbide processing parts, thus to trim carbide cutting tools will depend on the emery wheel to processing. As the groove of the drill out, the manufacturing, canned rebar with emery wheel etc are needed to process, especially the processing of arc workpiece with its best carbide method is to use the same emery wheel with circular arc to processing. I study is emery wheel repairing the crank rod system and the design of the projector system .
